AUTOMATIC CAR-STOVE-FIRE EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 2 78,236, dated May 22, 1883.

Application filed March 3, 1883.

To allwliom it may concern.-

Be it known that 1, JAMES F. Games, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful 1mprovement in Automatic Gar-Stove-Fire EX- tinguishers, which improvement is fully set forth in the following specification, reference being bad to the accompanying drawings, in which Figure 1 is a perspective view of the entire apparatus in position for use; Fig. 2, a perspective view of a portable apparatus in condition for use; Fig. 3, the detached key. Fig.

4 is a side elevation of the supporting-frame,

showing the operating mechanism onthe outside thereof. Fig. 5 is an elevation, partlyin section, of the fluid cylinder, showing the sheathed air-chamber; Fig. 6, a detached vertical section ofthe air-chamber and sheath. Fig. 7 is an elevation of the internal shaft. Fig. 8 is a detached elevation of the sheath, showing the disk or flange. Fig. 9 is an elevation of gear-shaft.

This improvement relates to that class of inventions described iig my application filed February 7,1883, and is for the purpose of providing an air-tight fluid-reservoir, in combination with a suitably-sheathed air-chamber, as a car-stove-fire extinguisher, which may likewise be rendered available for the purpose of extinguishing fire in a building, as here-- inafter more fully stated.

The cylinder, with convexo concave extremities, is made of copper eight and threefourths inches in diameter, (or may be made of any other suitable metallic substance and of greater or smaller dimension,) in two or three sections, the lower section for holding therequired quantity of a suitable liquid fire-extinguishing compound, and when the sections are united (by means of the couplings described in my previous application) measures about forty-six inches in length, and will su's. tain the pressure required for accomplishing the purpose, in manner hereinafter more particularly described. y

The fluid cylinder is vertically adjusted upon a metallic stand, E, and secured to the inside of the supporting-frame B, and is connected to the fire-box of the stove by suitable (No model.)

tubes, D D D, a cast-iron tube having been first placed into the aperture (previously made) at-the back of the stove to receive the extremity of tube D.

In order to prevent the possible displacement of the fluid-reservoir by an overturning of the car, an annular rim, X, having lugs (with apertures) X X, is placed over its concave top, and by means of the rods X! X and swivels X X bolted to the floor, as more particularly stated in my application filed February 7 Thereby-it becomes immovably fixed in a poor of any greater or smaller dimension or shape to suit the requirement, provided with a me tallic sheath, 0, having a suitable flange, 0", aroundthe lower part of same, being open at one end andconvex at the other, is made to slide closely around upon the chamber from itslower extremity upward a suitable distance, in order that the compressed air, when released from the air-chamber, as hereinafter more fully stated, shall not come in contact with the liq uid, but that its force, acting directly upon the sheath and its auxiliary flange, shall expel the same. The flange G is made of rubber and is permanently attached to the sheath, or may be made of cork or wood, or'of metal faced with ru bber,and as a modification it may be made of suitable diameter and placed upon the surface of the liquid under the sheath, or to take the place of it altogether; but in such cases the fluid-cylinder should be first tested in order to be satisfied that it is in all respects absolutely air-tight.

Upon the removal of the convex top of the fluid-reservoir the sheathed air-chamber and flange is placed within it immediately above the liquid, and is supported temporarily by springs a a, as at Fig. 5. Aperturcs are provided at each extremity ofthe chamber, as also a concavity upon each side of it, at a suitable distance from the top, as shown at V" V,

. to the four-sided terminals of the shafts V Vv Fig. 6, having an orifice directly in the center of each, with bushing around same, as at i 2, through which the horizontal shafts V V, working also in journals U U, attached to the inside of the chamber, are extended about an inch, and suitable four-sided attachments securedthereu'pon, as at S S, to work close up to the bushing. Upon the other extremities of the shafts eyelets are provided, as at e e, which are attached to the eyelets ec, provided upon the upper ends of the two vertical rods c c, and from thence the lower ends of same are connected by eyelets E E to the double eyelet terminal E, which is provided upon the lower valve-stem. The rods, however, are made in two parts and are connected also by eyelets, as at e e. The eyelets c are elongated, and the eyelets c are bent over, in order that when either shaft is employed by the mechanism hereinafter described to lift the valve from its socket the bent-over eyelet upon the rod connected to the inoperative shaft shall readily slide upward on the elongated eyelet, as most clearly shown at Fig. 5. The upper valve, W, is ordinarily held loose in the socketed bushing 10 (which is soldered to the chamber) by the stem-guide b, so that it may automatically open and close the aperture by the pressure employed in charging the receptacle. The bushing 10, attached around the exterior of the aperture, is threaded in order that a suitable air-pump may be secured to the same, as also to receive a cap, .20, which is correspondingly threaded, in which is provided a suitable orifice to admit the extension of the valve-stem W, which, when the air-chamber is charged, protrudes through the same, and, the end of it being threaded, a tap, 10, which is also threaded, is thereupon attached to hold the valve tightly in its place.

In charging the receptacle the tap and cap are of course removed, and any suitable airpump may be attached to the bushing and employed to compress the air thereinto until the required force is obtained, which may be equal to about one hundred and fifty or two hundred pounds to the squareinch, as will beindicated by attaching a suitable pressure-gage upon the top of the globe-valve WV, which. has been previously opened, as at W, Fig. 5. After charging the chamber the pump is detached and thecap andtap are replaced, and, the globevalve having been closed, the pressure 1 gage may also be detached. The recessed ends of the shafts S S (shown at Fig. 9) are attached (shown at S, Fig. 7) through suitable apertures in the reservoir by means of the collars 0 0 and couplings 0 0", which are screwed upon the threaded bushings o 0, provided around the apertures before stated. Upon the other extremities of the shafts S S the beveled cogs s s are attached, as at Figs. 1 and 5, which work into the correspondin gly-beveled cogs s .v, attached upon short horizontal projections which workin journals provided upon the sides of the supporting-frame and are connected to the toothed gearing 1*. (Shown at Fig. 4:.) The operating mechanism there shown consists of the toothed gearing 1', directly under which is a bar, R, attached near its center to the side of the supporting-frame, having similar toothed gearing at both extremities r 1". Attached also to the supporting-frame, directly under the bar It, is a pendulunrbar, L, which has a corresponding toothed gearing, 1*, upon its upper end, with elongated fulcrums attached thereunder to the frame also, as at 10, Fig. 4,

and a flattened weight, P, at its lower extremity, the latter having rollers attached upon the sides. At the bottom of the frame are attached parallel curved planes V V, with a suitable guideway between them and a depression at the center of the are.

To prevent the premature discharge of the liquid, and the consequent extinguishment of the fire, the pendulums ordinarily hang out of gear (or engagement) with the toothed extrem ity of the bar It, and are so held by the governor-bar G until the apparatus is inclined to an angle of forty-five degrees. When, therefore, the deflected car attains such an angle in any direction, one of the pendulums must inevitably be released and thrown into gear, which, then acting (through the mechanism shown at Fig. 4) upon the beveled cogs s and s, operate shafts S and V, thereby lifting the escape-valve V from its socket, as shown at Fig. 6, when the compressed air instantly strikes the sheath with great force, causing the springs a a to yield, sending it and thc flange down upon the liquid, which is in consequence driven through the tubes into the fire-box of the stove.

The convex extremity of the sheath dc scends into the concave bottom of the reservoir, thereby forcing oiit the whole contents. Thus it will be understood that when, by an overturning of the car, the reservoir becomes upset or is entirely turned upside down, the

continuous discharge of the liquid cannot be obstructed. I

In a fire-extinguisher for-a building, the reservoir is secured vertically upon awheeled truck by annular ri m X, lugs X X, rodsXX, and swivels X X, which are bolted to the flooring of same, as shown at Fig. 2, and is provided with a vertical tube coupled to its concave bottom, upon the upper part of which hose is attached. The truck being provided with axles and wheels, (and a suitable handle,)

the whole can be readily moved about the building and a fire extinguished by attaching the key and turning the shaft, in order to lift the escape-valve. and then directing the discharge of the fluid through the hose-pipe.

Having thus described my invention, whatI claim as new, and desire to secure by Letters Patent, is

1.
